Q35 connection to PC is sporadic

I’ve paired my Q35 headphones with my new PC, but the sound comes through only intermittently. I’ve already unpaired/re-paired with no luck. Works with the wired connection. I have also paired the headphones to the app on my Galaxy S21. I tried turning off Bluetooth on the phone to see if it was interfering, but still have the issue.

Delete the default bt driver given by MS and install the bt driver from the bt card manufacturer instead.
